mounting terrorist threats at the winter olympics two weeks away now, prep rags to protect the sites are ramping up. That is not tamping down the competitive spirit of athletes speaking out for the first time go the threats. ABC's Brian Ross here with that. Good morning. If the terrorists in Russia get their way their prime targets would be the young athletes who have worked so hard to get to the olympics and there's no doubt security concerns are weighing on the American men and women who are heading to sochi. For the first time, women are being allowed to enter the ski jump competition and for the three American women who race down a 350-foot-high ski jump to qualify for the olympics, not a lot seems to scare them. Even the news out of sochi. There you go. I've been watching the news. I'm Reading about it and, unfortunately, it's just something that you have to deal with and keep plugging along. Reporter: It took a long legal battle for the women announced Wednesday to be allowed into the olympic event and they told ABC news, they have no intention of letting the terror threats distract them. Security isn't my top concern mu . The only thing I said is bring a jacket that doesn't scream America to my family. Reporter: The threats are real. Still no progress in tracking down the alleged suicide bomber who authorities believe is already in sochi. And the white house reported an increase in telltale signs of terror attack planning. We have seen an uptick in threat reporting prior to the olympics, which is, of course, of concern. On a positive note the olympic torch relay continues across Russia. So far without incident before it heads next week into dagestan and chechnya which are the strongholds of the terror groups that have threatened to disrupt the olympics with suicide bombers. They are, Brian, thanks very much.
